链轮的安装要求:
1、根据规范精确选用传动链轮类型。
2、按精确方法将主、从动链轮设备到位,且拧紧紧固件使其到达规矩力矩恳求。
3、装上传动链条并调整好松紧度后,检查链条与链轮配合是不是顺利、共面,且与链罩无干与。
4、检查设备传动链轮的方位(变速器输出副轴、轮毂等)情况是不是杰出,否则须维修或更换有关件。
链轮使用过程中的注意事项:
1、从动链轮应有防松方法与措施。
2、链轮和链条最好一起更换,若只更换其中之一,会加剧两头的磨损。
3、要守时地清洗及光滑传动链条、传动链轮,以前进其运用寿命。
4、从动链轮装车后,应使用调节器和后摇架刻线将后轮轴调正,这么既可避免后轮跑偏,也能避免链轮与链条的早期磨损。
